Silent Fan mode with total Compensation

Hello everyone,

I am currently testing our ESS, that consists of 3 MP2 3000 24V (3Phase) and that is always connected to the local grid.

My current problem is, that the fan in the Multis are clearly audible at night. I now want to enable the "silent fan" mode at night, but I have a few questions, regading that mode:

On the Victron homepage it just says: "The result is that during invert the product will switch off sooner".

In Offgrid systems, it is obvious to me that this means, the multi will just shut down due to overtemperature. But what happens in a grid tie system? Does it just throttle down and invert less power, getting the rest from the grid? Or does it also just shut down? (This would be kind of dumb...)

Do you know anything more about this mode?

Thanks in advance!

Then I need extra energy for the cooling, so nope... Not an Option.

That's interesting. Where can I set the "silent fan" mode? Can I configure times when it should use it? For example from 22:00 till 6:30

You have to install it as an Assistent, just like the ess. It has to be configured on All units. One unit can then be controlled with an external Switch, or relay.
